WARNING: Extremely long comment ahead!
To be quite honest, my opinion of Hero Factory has had several stages. My first stage was just total rage and hate, due to it being BIONICLE's replacement and end. Then, later, I just accepted it and decided it actually wasn't all that bad. Oh sure, the show was stupid enough, almost as bad as Chima, and the sets weren't initially all that good, something that I have actually disproven recently because I obtained the original Stormer set with an order of parts off of eBay, and realized just how much personality and detail they gave him.....just to make him the stereotypical leader tough guy in the show. Then 2.0 came around. I didn't actually get any of the sets from that year until after 3.0, but I was quite interested, but was really wishing you could just look at any of the figures without a namecard, and say, "Hey! That's Furno! Look at his helmet!" This was probably because BIONICLE always had that factor. The Hau has always looked like a Hau. Enough said. Then 3.0 happened. I am going to say something that a lot of people are going to dislike. I liked 3.0 quite a bit. In fact, my first Hero Factory set was Furno 3.0. I really loved the style and feel it had, although the "movie" was complete rubbish in almost every way. Once again, however, you couldn't look at any of those characters and tell they were who they were supposed to be. Breakout, however, blew the other years away, in my opinion. We got recognizable characters, cool new Thornax Blaster molds, and some really solid looking sets. I have the Evo set from Breakout, and to note, I think it's the best Hero Factory set yet! Then Brain Attack happened. Recognizable helmets, sure, but the visors don't work on most of them. The worst part? LEGO was taking something seriously major from BIONICLE. Rubberized mind controlling parasites sent by some mysterious villain whose name we don't know? Sounds an awful lot like Kraata send by Makuta doesn't it? Krana? Heck, even the Mistika Makuta's Nynrah to an extent, served the same purpose of controlling the enemy. Then Invasion from Below came along, and I started getting suspicious. Once again, the quality had gone down for the most part, but things were getting closer and closer to a BIONICLE style. We had spiders, like Visorak, we had Machines, or rather Exo-Toa, and then.....we got a leak showing BIONICLE sets with miniature spiders as the villains. I'm pretty sure that Hero Factory was nothing more than a test run of a new building system to replace the Inika Build, but placed in another theme so as not to alienate the current fans, allowing them time to get used to it. I don't hate Hero Factory anymore. If I am correct, than it has done its job, and done it well.
